What would you like to be improved?

When Runtime.getRuntime().availableProcessors() is not obtained correctly or the obtained value is less than or equal to 2, the default value of iceberg is 2, AMS is congested in thread iceberg-work-pool-xx.

How should we improve?

Add parameters in config.yaml to overwrite the value of iceberg.worker.num-threads.

This is a java property used by the Iceberg and it can be set in ams.sh like '-Diceberg.worker.num-threads=xxx'.
